Application tiled February 23,1909. Serial No; 479,488.

To all whom t may concern:

jBe i known that We, EUGENE D. C. BAYNE and Lawrance A. Solanas, citizens ofdthe United-States, and residents of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Automatic Machines for Laying adhering Cords or Threads Upon a Stationary Mandi-el to Form an Unvvoven Fabric, of which We declare the following to be a full, clear, and exact description, Ksuch as will enable others skilled in the artto which it appertains to maire and use the same.`

.The objects of the invention are to provide an automatically acting machine for the construction vof a section of hose pipe or analogous tubing of any desired length from one continuous thread orthreads. This hose is formed .of a fabric composed of layers of univoven cord or thread, hereinafter mentionedfas threads, and these layers are composed of parallel rows of threads adhering together, and adhering to the adjacent layers, each layer of thread crossing the adjacent -layers at a definite angle, and preferably alternating in direction, one layer of thread running longitudinally in the hose and the adjoining layers running transversely or spirally around the same, or one layer of longitudinal threads to any desired number of spiral threads.

This machine is designed as an improvement upon our previously invented auto matic machinery for the manufacture of un- Woven tubular fabric With rubber, in which the fabric was formed upon a rotatable mandrel by means of highly polished director Wheels which could be automatically moved to apply the thread either spirally or longitudinally thereon. This former machine had a two-fold use. First, it Was provided with automatic mechanism for rotating the mandrel periodically, and for simultaneously providing a4 rapid longitudinal movement to the director Wheel or Wheels so that they could apply the longitudinal rows of threads tothe forming mandrel. And, secone, the mandrel rotates at constant rate 4of speed, and the director Wheel or Wheels were y given a slow longitudinal movement so as to 'enable theml'to applyl the thread in spiral .rmysnpon the mandrel, and means Were pro- -videdi'for alternating these movement-s ,to

provide alternately spirally and longitudinaily laid rows of threads thereon. In this former device other important features were the tension and pressure regulating devices, for the thread., and means for laying'tlie threads in rubber. This mechanism has been 4described in our previous applications for Letters Fatent of the United tates bearing Serial Nmnbersllflm, 467,621, and Letters Paten-t NOS. einen, 885,220, and 897,339.

ln the present machinev hereinafter described the important features of tension and pressure devices are retained, and also the means for coating the threads With rubber or other tenacious and vulcanizable material, and the polished director and guide Wheels. lt is better adapted, however, for manufacturing longl lengths of hose or tubing. 1

rl`he importantfeatures of novelty and improvement in this machine, therefore, are found in the employment of a stationary mandrel which can therefore be supported 4at intervals, and in automatically operating mechanism, for revolvingthe director Wheels which vapply-the thread, and their supports, and thread supplying' devices around the mandrel; and in providing a combination and arrangement of the various parts such as will adapt and utilize them for this .material change in the general action and mode of operation of the machine.

To permit of manufacturing long lengths of tubing, the thread is laid by means of director Wheels mounted in a drum secured Within a carriage and which revolve about the stationary mandrel, which is supported upon end supports and removable intermediate supports spaced at intervals thereunder. These intermediate supports are raised and lowered under the control of thesaid carriage., The drum is given a combined longi- .tudinal and circumferential movement about the mandrel vto enable the directorivheels to -l apply .the spiral rows 4of threads thereon,

'and is given .an intermittent longitudinal movement relatively to Athe mandrel to enable the director Wheels to apply lthe longitudinal rows :of threads thereon. Each of these movements can .also be reversed at vaillto `change the direction of laying the thread.

4The carriage is designed. .to conv f 'l ldrum and all the mechanism and appl required in laying thread upon the man .Ulli

including the thread itself, and this mechef` nism differs only'in arrangement of parts and in detail J construction from that ein ployed in the former machine hereinbefore mentioned. The carriage is mounted in lon'- gitudinal guides upon a suitable bedplate', and the drum is rotatably secured therein.

The appliances within or :attached to the drum and rotatable therewith, may be de scribed as, thespools upon which the thread is wound prior to passing over the director wheels, a tension device for each thread and guide wheels therefor; 'reservoirs stored with liquid rubberand mechanism for-exerting a constant redetermined degree .of pressure upon the1r contents, nozzles for applying va stream of "liquidrubber in ad-l vance of -the threads as they` are being laid upon the mandrel, spindles'upon which'di- 'rector wheels are mountedand springsfor exerting a pressure vthereon so as to adapt- .them, for use with varying sizes of man-y diels; and bracketssecured tothe drum-in which the spindles are mounted. in such a manner that they are a Q present the director wheels, either lon'gltudinally or transversely ofthe mandrel', `to' ac commodate the two general -directins'for` laying the threads -k The drum is provided with ratchets which are operated periodically by means of suitable mechanism, a portion of which'is se-y cured tothe bedplate'of themachine and are designed to give a slight intermittent rotary movement to the carriage at one end of its travel when the longitudinal thread is being laid equal to the diameter ofthe thread. The drum is 'also provided with gearing arranged to produce a regular rotary movement thereof when the'spiral rows 1 of thread are being laid. All the movements -movements df the carriage vfor depressing these suppo'itts, to enable the carriage and drum to pass, and for restoring these supports fto position as soon as the d/arrier has passed by them.

It also comprises mechanism forl looping the thread and for holding the looped end 'of the thread during the longitudinal movements of the carriage at the end of its ywhilethe next row is being laid; a'nd avel,

l l r revolving the loop-holding devices while the dj ustable, soas' te" K `for the purposes described.

intermittent ratchet' movement of the drum is taking place, to properly .locate the'thread holder for thenextlaid row of thread.'v

The invention also has reference to autoniatically lacting reversing mechanism for 'tlie worm shaft or feed screw arranged to operate at each end of the tubular fabric, and adjustable so thatany predetermined length offabric can be manufactured on the same mandrel. l

' The invention furthercomprises the comhina-tion and arran ement of parts, as hereinafter described, s own in the accompanyin the claims. A

These views show preferable forms.

of construction of the automatic mechanism In these views 1 represents theanachine bed provided with V-shaped guides` 2,2, in which the hood-shaped carrierQ is adapted to/slide 'longitudinally thereof. This bed 'is supported upon legs, 3,. 3, of convenientheight. At opposite ends of this"bedplateg-areshown bearings 4J, 4, yfor the formingmdpdrel or hose shaft 5, and similar bearings' for the nemer main actuating' feed screw G, `from which t-he movementsol the automatic thread laying mechanism are derived. This' feed screw is rotated in opposite directions by means of pulleys T and 8 respectively, one being driven by means of a cross belt and the other by means-of Va. straight belt. Either pulley can be thrown into connection with the v.feed screw 6 by means of any convenient form of clutch such as the friction clutch shown at 9; and a shifting rod 9 automatically 'operated by. means of fingers 9, upon the shifting rod 9 which are adapted to be engaged by the carriage 2 at each end of its travel.

The carriage 2 incloses and'conveys nearly all ofthe mechanism required for laying the thread upon the mandrel 5, in-,alternating longitudinal end spiral rows, to torni the tubular fabric. V'Vithin thecarriage is rotatably mounted the cylindrical drum 10,

` and to the inner sides of this drum and rotatable therewith are secured brackets 11, 11', upon which spindles l2, l2 are secured. Upon these spindles are mounted the spools or cores 13, 13', which are conically shaped to enable the threads to reel ott quickly and Without interference. Thence the threads 'pass through `guidingeyes, 14,111, so that the threads will feed from' the cores equallyv well in both directions of travel of the carrier. These eyes are. formed in brackets 15, 15, secured to the drum 10. rlhese spools of thread 4and guiding eyes are mounted diainetrically opposite eachv other and revolve ooncentrically about the mandrel. The threads, after passing through the guiding 4eyes are fed to tension devices 1G, 16, similar to those described in our prior applications and thence pass over guiding` wheels 17, 17 to the spring` pressed applicator or director wheels 18, 1S,.which press the threads upon the coating 19 upon "the mandrel, when the lirst layer is laid, or upon previous layers ol thread thereon. the thread passes from the director or thread applyingwheels to the mandrel, it is laid in a small stream of liquid rubber ejected through a tube or nozw ale such as 2'), 20', upon the mandrel, in advance of each director wheel, which thus forms a body or rubber matrix inclosing the threads and when vulcanized causes the several threadsl and layers to adhere together in a homogeneo's mass. The liquid rubber is stored preferably in a separate cylinder Q1 and 2l for cach nozzle, and is placed under a constant pressure in each cylinder, so that the liquid will tlow with perfect regularity, by means oi the piston, 22, and 22, a piston rod Qa, and ift which is preferably made tubular, for the introduction the liuid rubber therethrough, ayoke 25, slidlinglv movable on the cylindrical projectionldot the'drum, and the-bell crank lever Q17 pivotcd upon the arm 28 noon the carrier il',

which engages the yoke 25. a weight Q9 on the long arm of the lever 27 is adjustable thereon to give the necessary compression to vthe pistons. A exible pipe, 19', 19", for

in spindles 30,3Q, rotatable through an arc, vo'QO degrees each in their bearings, by

means of set collars 3l. 31', and projections 32, 32, which engage the slots 33, 33 in the bearing 34, '311'. rlhese bearings are mounted upon the brackets 35,- 35', secured to the drumv and rotatable therewith. Springs 36, 36 exert pressure upon the spindles to' keep them in engagement with the mandrel and in this manner permit. of the use of varying` sizes of mandrel, rThe adjustment of these spindles also permits of their being 'placed either longitudinally or transversely ot' the mandrel to lay both longitudinal and spiral layers of the thread.

The worm. shaltv G passes througn bosses 37, 38, on the carriage and a screw B9 in one of these bosses enters the groove G in the .worin shaft. A roller 40, relieves the frio tion upon the end or" this screw. ln this manner the feed screw will operate to move the carriage longitudinally ot' the bed 1 in each direction according; to the direction oi" rotation ot' the screw. This change oi"l rolation is accomplished by means oit the 'inllcys TandS and clutch 9 as previously descrilnal. The clutch 9 is operated by means of a lever l1 which is lorked at each end, one end grasping' the clutch b ody 4and the other end operated by the adjustable set collar #l2 on the shifter rod 9. The lever i1 is pivoted ai 4Q on a bearingl lf3 secured to the bed, The shifter rod is provided with adjustable finger collars 9", which engage the carriage 2f in its travel, and the carriage imparts motion to the shifter rod which ope the lever L11 and throws the clutch .l, thus releasing the activo pulleyv and throwing` the other pulley into action and reversing the direction of rotation ci the leed screw and therefore the direction o i travel olf the carriage 2. ln this manner the carrir je travels successively backward and torwarf, laying` 'the threads lonlfxitudinally two at a time, one on each side ot' the mandrel and diametrically opposite to each other. lfn the meantime` the drum intermittently rotated to a distance equaling` the thickness ot one thread, so that when' one-half of a revolution has been made a -compl.cteocoatinuW has been placed on the mandrel oi longitudi- "yally placed threads. This interi'nittent rotation of the drum is accomplished, as follows -The cylindrical drum 10 is given an `intermittent lrotary inovemcntsat each end-ot the travel ot' the carriage by means ut ratchet wheels, fil, i, and 'l-G. secured to one end thereoiC and rotating` therewith lili) A. sleeve50, having,a sliding lit on-the feed screwr isattached to the carriagein such a manner as to ermit a revolving motion around the feev screw, which is limited by an adjusting screw 51 on this sleeve, engaginge-stop 51 on the carrier 2. vThis sleeve has 'an arm 52 on its upper side carryin a pawl 52 held in-engazgement with the rate et teeth ouf one of the ratchet wheels, 44, 45,

Aor 46, by means o f a tension spring 53. On

the lower end of this sleeve' are two cam 'fingers I-I and I which at the end of the ear- 'riers travel engage respectively a cam 54 or 55 secured to the bed 1 at each end thereof, a'nd impart a slight rotary movement to the cylindrical drum 10 through the pawl. 52 and engaging ratchet wheel. The upper'arm on this sleeve is also attached to a link 56- 'diameter of the threads and -tlie number of threads to be laid around the mandrel, one ratchet tooth to each thread. These ratchet wheels or rings can be made in hal-ves for *conveniencel in changing.

In order that a continuous thread may be laid longitudinally along the mandrel, iirst iu onedirection andl then in the other, it is necessary that a loop should be formed at each .eXtreme end of the fabric.

To secure'this loop at the right positioma loop holding finger 60 foreach thread is pivoted at 61 upon an arm (i2 which is pivoted inY turn upon a spring collar G3, which slightly vgrlps the mandrel, but can be turned thereon 'when some pressure is applied thereto. This collar is'providedwith a set screw 63 moving in a roove 64 in the mandrel to prevent'longitu inal movement thereon. The arm 62 is held pressed against the mandrel by means of a tension spring 65. The loop-holding Iinger'GO is provided' with a looping point 66 in its edge.. And the linger at its outer edge is provided with flattened projection 67. The spindle carrying the director wheels isprovi'ded with cam faces l68 and 69, and as --it' approaches.v the holding finger the 4director wheels passvover the finger: andthe camsurface vG9 engages the projectionI y67 on the `finger and thus .raises the looping 'point,releasing it from the loop already formed against the pressure of a spring 70. The spindle traveling still' farther, thefcam surface 68 engages the sur-- face Iof the' said projecting arm. GT, and rotates the distance equal. to the diameter of one thread. Traveling slightly farther, the flattened arm 67 passes between the jaw 72, 72, of the spindle, and at that instant the drum is rotated by means of the pawl 52 and ratchet wheel thus carrying with it the collar G3 and attached parts, and leaving the projecting pointI (36in position to form the loop in the thread on the reverse movement of the carriage. As soon as the spindle returns the point 6G drops against the mandrel the thread is looped over it. This device for looping the thread is employed at each `end i of the machine and is duplicated at a point diametricallyoppsite on the same collar 63. The thread is laid spirally upon the mandrel by means of the following automatically acting instrunientalities First, the roller 40 is placed in eneagement with the slot in the feed screw. "This feed screw also has a key slot 81 throughout its length. In a hub 37 on the carriage isa sleeve 82, which is 'provided with a key 83 adapted to slide in this key way, on the worm shaft. This sleeve rotates constantly with the feed screw. A set screw '84 engages a circumferential groove inthe sleeve 82,' thus attaching the sleeve to the carriage. This sleeve is provided with a gear S5, on its projecting end attached thereto by means of a set screw, so that the gear can be released therefrom when laying the longitudinallayers. This` gear engages the tram' of gears 86, 87, 88, 89, and 90,.the lastnamed gear being secured upon. a projectingboss 91 upo'nthe drum, which is thus driven at a high speed. The speeds of the drum and feed screw are so related as to cover the mandrel closely with `spiral rows of threads as `the carrier traverses the manl drel from one end ,to the other, and a layer can be laid in either direction by thel revers-4 ing means for the worm shaft previously described.

The next step is' to place the director wheels transversely ofl the mandrel. The carrier and drums are then in readiness to lay the thread. l

The mandrel and vfeed screw being long, it

is necessary to support them at regular in- 1 tervals, and that these supports should, be automatically 'removed to make a' passhge for the carriage and immediately restored to position yas soon as the carriage has passed.

This is an important feature of the invenl tion since the long mandrel and screw would vibrate injuriously to the accurate laying of the fabric if not provided with supports in# termeeliate of their ends. To accomplish this result, diametnically opposite supporting arms 92amI provided for the feed screw andare mounted upon transverse shafts 93 1n the bedplate,and arranged at regular intervals, such asv every five feet thereon.

These supports 92 are provided. with forked Cil 4heads Se. The removable supports for the mandrel are constructed as follows :wleyed to each shaft 93 is the adjusting` hub 95 whichis provided with two diametrically o posite arms 96,and radially movable on tlese arms-are the supporting heads 9T for lthe mandrel. sleeve 98 upon each shaft 93 1s secured to the bedplate at 99, and is 4provided at its inner end with a vcam groove 100, out in a tlnage` 101. A port-ion of each .mandrel support is threaded at 102, and a nut 103 placed thereon. This nut is pro vided with an extension 104, which is grooved at 105, and inserted in a collar, 106. .a set screw 10.7 attaches the extension rotatably in the collar. The face of the collar adjacent to the flange 101 `is flattened so as not to. rotate on the arm fland a roller 108 upon the screw 108 engages the cam groove 100fin the iiange 101. The shafts 03 are rotated by means of the exterior' stars 109, 109, ind the depending arms 110 upon the carrier one arm being at each end of the carrier. its soon as one of the arms 110 strikes the star, the shaft rotates through 00 degrees and the supports 94 for the worm shaft are rotated with it to release the teed screw. llt the same time the arms 96 are rotated also through 90 degrees, and the rollers 108 movingr in the ylined cam groove 100 are drawn inwardly, and thus draw down the supporting heads 97 for the mandrel, with them, thus releasing the mandrel, from contact with the respective head in contact therewith. A different action is required for the mandrel supports, from the feed sorewsupports since the. coated threads on the mandrel cannot be disturbed from their positions by the frictional action ot" its supports. As soon as the carriage has passed, the arm 110 at the other end of the carriage turns the star 109 through another 90 degrees and brings up the opposite supports in reverse manner underneath the mandrel and feed' screw.

Both the mandrel and feed screw can be made i'nsections attached together in any `convenient manner, so as to provide 'for the manufacture of any desired length ol tubing. The mandrel can be withdrawn from the machine by releasing the set screw 112, and by screwing the supporting center out of connection with the mandrel. lt is obvious that by suitably adjusting' the relative speeds of the gearing onv the drum and the feed shaft it would be possible to make the tabric from one continuously and closely laid thread; or from any multiple number of threads and also from a thread or threads of any desired diameter all such modifications being' within' the spirit o'l' the invention, and relative to thc mandrel and the parts of mechanisn'i thereof, as described in these specifications, necessary to cbnstruct a tube, the same maybe placed in a horizontal or perpendicular position or any anglenecessary or convenient inthe operation of the claim as new and desire to secure by Letters Patent, is
